Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Westwell are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we’ll need

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
Construction mastic in Westwell
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. Our aim is joints that pass at the first inspection, area by area through the programme. We work on floor and skirting junctions, window and door perimeters and brick and block movement joints, and the usual reasons a site gets in touch are different trades sealing to different standards and existing joints on a refurb that need cutting out and resealing. Facilities teams, main contractors and managing agents in Westwell tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Westwell, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
- Joints damaged after sign-off by following trades
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Quantities, in metres or numbers
- Which sealant the job calls for
- Any access equipment needed
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
However big the job, the same details help:
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Anything awkward about access or site hours
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
FAQs: Westwell
Can you take on a job at a hospital such as William Harvey Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does your area include sites such as Eurogate Business Park, near Westwell?
Yes. We cover Westwell and the area around it, including industrial estates, business parks and retail parks such as Eurogate Business Park. A few photos and the unit address let us price the work.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

What the job involves on each surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.
After the work
A few simple habits keep the new joints working:
- Allow flexibility for external sealing in damp or cold weather
- Protect sealed areas from following trades
- Keep product details for future maintenance
- Use the product the specification names
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
When to call us in Westwell
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.
Site and facilities staff are often the first to spot these:
- Failed sealant in an existing building being refurbished
- Frame perimeters left unsealed or poorly sealed
- Sealant knocked or painted over by other trades
- A mastic package split between trades with no clear owner
For a contractor working at a hospital such as William Harvey Hospital, which lies south-east of Westwell, perimeter and facade sealing is planned around patients and deliveries.
